    Abstract: Multiple energy sources, such as a laser and electrical current, are employed, in close coordination, spatially and temporally, to clean a sample, vaporize its material and excite vapor atoms for the purpose of atomic emission spectroscopy. These methods permit better monitoring and control of the individual processes in real time, lead to higher consistency and higher quality optical emission spectra, and enhance the measurements of non-conducting solids, liquids and gases. Additionally, a portable instrument is provided with both laser source and spectrometer optically coupled to a hand-holdable unit.

    Abstract: A two-chamber electron impact emission sensor effective for monitoring vapor flux of materials in the presence of interfering species is described. The sensor includes two independent electron excitation regions and one photodetector for monitoring emission from excited species from both chambers. Copper vapor flux from an evaporation source was accurately measured in the presence of interfering H2O vapor, and Ga vapor flux from an evaporation source was accurately monitored in the presence of interfering CO2 gas. The invention permits deposition rates to be monitored using electron-impact emission spectroscopy with significantly improved accuracy in the presence of interfering gases at high partial pressures.
